Collapsible Bottle Apparatus

ABSTRACT

A collapsible bottle apparatus includes a body member having a flexible liquid reservoir, a base, and a primary thread adapter. The primary thread adapter defines an open interior space in communication with the reservoir. The body member is movable between an extended configuration and a collapsed configuration in which the reservoir is disposed in the interior space of the primary thread adapter. A retaining ring includes a top wall defining an aperture and a continuous side wall selectively coupled to the primary thread adapter. A primary dispensing member is selectively coupled to the retaining ring and includes a nipple extending upwardly through the aperture when the primary mounting section is coupled to the retaining ring. An auxiliary thread adapter enables an auxiliary dispensing member that includes a spout to be selectively coupled to either a water bottle or juice bottle having different neck diameters.

BACKGROUND OF THE INVENTION

This invention relates generally to bottles for feeding infants andcontainers that dispense drinks to toddlers. More particularly, thisinvention relates to a bottle apparatus having a reservoir that iscollapsible for storage or transport and that is adaptable to connect toa conventional water or juice bottle for use by a toddler or youngchild.

When traveling or attending an event with a baby, a mother or othercaregiver must often prepare multiple bottles and pack other supplies ina bag. However, if the plan is only to be gone for a short time, one ormore bottles may be packed in a purse. In either case, the size of thebottle can be a real space challenge. In addition, a care giver havingan older child may also need to pack a “sippy cup” having a spout thatis more appropriate for a toddler. Again, space for these supplies is anissue. Then, water or juice must be poured into the sippy cup and thelid replaced before the cup is ready for the toddler to drink from.

Various devices have been proposed in the art for a collapsible babybottle so as to reduce the amount of storage space for an empty bottle.Although assumably effective for their intended purposes, the existingdevices do not provide a collapsible bottle apparatus that may beselectively adapted to connect to a collapsible bottle reservoir or to aconventional water or juice bottle.

Therefore, it would be desirable to have a collapsible bottle apparatushaving a nipple style dispensing member selectively coupled to acollapsible liquid reservoir and a sipper spout dispensing member thatis selectively attachable to a conventional water or juice bottle.

SUMMARY OF THE INVENTION

A collapsible bottle apparatus according to the present inventionincludes a body member having a flexible reservoir and a base coupled toa lower end of the reservoir and having a primary thread adapter coupledto an upper end of the reservoir, the reservoir defining an interiorarea configured to selectively contain a liquid. The primary threadadapter includes a continuous side wall having a threaded outer surface,the primary thread adapter defining an open interior space incommunication with the reservoir interior area. The body member ismovable between an extended configuration in which the base is displacedfrom the primary thread adapter and the reservoir is expanded and acollapsed configuration in which the base is adjacent a lower edge ofthe primary thread adapter and the reservoir is disposed in the interiorspace of the primary thread adapter.

A retaining ring includes a top wall that defines an aperture andincludes a continuous side wall having a threaded inner surface that iscomplementary to the threaded outer surface of the side wall of theprimary thread adapter such that the retaining ring is selectivelycoupled to the primary thread adapter. A primary dispensing memberincludes a primary mounting section selectively coupled to the retainingring inwardly adjacent the top wall and having a nipple extendingupwardly from the primary mounting section, the nipple extendingupwardly through the aperture when the primary mounting section iscoupled to the retaining ring.

Therefore, a general object of this invention is to provide acollapsible bottle apparatus having a modular construction forselectively providing milk or formula to an infant or attachable to aconventional water or juice bottle for dispensing the contents therein,respectively.

Another object of this invention is to provide a collapsible bottleapparatus, as aforesaid, having a flexible reservoir that expands whenfilled with liquid and which may be collapsed inside of a primary threadadapter when empty.

Still another object of this invention is to provide a collapsiblebottle apparatus, as aforesaid, that includes an auxiliary threadadapter having two sizes of threads so as to be selectively coupled to aconventional water or juice bottle.

Yet another object of this invention is to provide a collapsible bottleapparatus, as aforesaid, that is easily convertible between use with thereservoir and use with a conventional water or juice bottle.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A collapsible bottle apparatus according to the present invention willnow be described with reference to FIGS. 1 to 5 d of the accompanyingdrawings. The collapsible bottle apparatus 10 includes a body member 20having a primary thread adapter 30, a retaining ring 40, a primarydispensing member 60, an auxiliary thread adapter 70, an auxiliarydispensing member 66, a cap 50, and a base 28.

The body member 20 includes a reservoir 22 that is constructed of aflexible material, such as a thermoplastic elastomer (“TPE”), also knownas thermoplastic rubber. Preferably, the TPE material is transparent ortranslucent so that a user can observe a level of liquid containedtherein. The reservoir 22 includes a continuous side wall 24 having agenerally cylindrical configuration and defining an interior area. Thereservoir 22 is sealed and configured so as to contain a liquid in theinterior area thereof, such as baby formula, although the reservoir 22may include an open top for refilling and for dispensing the liquid. Thereservoir 22 may also include graduated alphanumeric or graphic indicia26 imprinted on the side wall 24 that is indicative of a volume ofliquid in the reservoir 22 (FIG. 1 c).

The body member 20 includes a base 28 coupled to a lower edge of thereservoir 22 (FIG. 2 a). The base 28 may have a generally circularconfiguration although other configurations would also work. The sidewall 24 of the reservoir 22 extends upwardly from the base 28. The bodymember 20 also includes a primary thread adapter 30 having acylindrical, annular, or ring-shaped configuration, the primary threadadapter 30 being coupled to an upper end of the reservoir 22 (FIG. 2 a).The primary thread adapter 30 defines an open top, an open bottom, and abore therebetween. The primary thread adapter 30 includes a continuousside wall 32 having a threaded outer surface 34 and defining an interiorspace in communication with the interior area of the reservoir 22.

The body member 20 is movable between an extended configuration (FIG. 1c) and a collapsed configuration (FIG. 1 b). More particularly, thereservoir 22 expands when filled with a liquid and the base 28 isdisplaced from the primary thread adapter 30. By contrast, when thereservoir 22 is empty or substantially empty, the base 28 may be movedto a position adjacent a bottom edge of the primary thread adapter 30and the side wall 24 of the reservoir 22 is folded up into the interiorspace of the primary thread adapter 30 (FIGS. 3 b and 3 c).

The side wall 24 of the reservoir 22 may include a plurality of segments36 a, 36 b, and 36 c, each segment being separated from an adjacentsegment by a ridge or a line of weakness 38. Each line of weakness 38defines an axis about which adjacent segments will fold when moving thereservoir 22 to the collapsed configuration. Adjacent segments may havedifferent diameters. In one embodiment, the reservoir 22 may include amore gradual change in dimension rather than being segmented.

The retaining ring 40 includes a continuous side wall 42 so that theretaining ring 40 has an annular or ring shaped configuration. Theretaining ring 40 includes a threaded inner surface 44 that iscomplementary to the threaded outer surface 34 of the side wall 32 ofthe primary thread adapter 30 such that the retaining ring 40 may beselectively, threadably, and releasably coupled to the primary threadadapter 30 (FIGS. 1 b and 1 c). The retaining ring 40 includes a topwall 46 defining an aperture 48.

The primary dispensing member 60 includes a primary mounting section 62and a nipple 64 extending upwardly from the primary mounting section 62(FIG. 2 b). The primary dispensing member 60 is constructed of athermoplastic elastomer that is itself movable between a collapsed andextended configuration. It is understood that a distal end of the nipple64 defines a small outlet or opening for dispensing a liquidtherethrough. More particularly, the primary mounting section 62 mayinclude a generally planar flange having a diameter that issubstantially similar to an inner diameter of the retaining ring 40 suchthat it may be situated inwardly (or interiorly) adjacent the top wall46 of the retainer ring 40 in a friction or snap fit arrangement. Whenso positioned, the nipple 64 extends upwardly through the aperture 48 ofthe retaining ring 40. It is understood that when the primary dispensingmember 60 is coupled to the retaining ring 40 and the retaining ring 40is coupled to the primary thread adapter 30, liquid from the reservoir22 may be dispensed through the nipple 64, such as by a baby sucking onthe nipple 64.

The collapsible bottle apparatus 10 includes a cap 50 having acontinuous side wall and a closed top 52. The cap 50 has a generallytruncated cylindrical shape that defines an open bottom and interiorcavity. The side wall of the cap 50 has a diameter slightly larger thana diameter of the retaining ring 40 such that the retaining ring 40 isconfigured to selectively receive the cap side wall in a friction fitrelationship. As shown in FIG. 4 e, the retaining ring 40 may include alower portion and an upper portion with a ledge 49 separating the twoportions, such that the cap 50 may be coupled to the upper portion ofthe retaining ring 40 in a snap-fit configuration and, in doing so,covers the primary dispensing member 60. The upper portion of theretaining ring has a diameter slightly smaller than a diameter of thelower portion such that the cap 50 is selectively received onto theupper portion. The function and configuration of the cap 50 is bestunderstood by comparing FIG. 1 b in which the retaining ring 40 andprimary dispensing member 60 are uncovered and FIG. 1 b in which theupper portion of the retaining ring 40 is covered by the cap 50.

One embodiment of the collapsible bottle apparatus 10 includes anauxiliary dispensing member 66 having a construction substantiallysimilar to that of the primary dispensing member 60 described aboveexcept as indicated below. The auxiliary dispensing member 66 includesan auxiliary mounting section 68 that is selectively and removablycoupled to the retaining ring 40 inwardly adjacent the top wall 46thereof. It is understood that the auxiliary mounting section 68 may becoupled to the retaining ring 40 in a friction fit (i.e. snap fit)relationship as is known in the art of infant bottles and nipples. Theauxiliary dispensing member 66 also includes a rigid spout 69 extendingupwardly from the auxiliary mounting section 68 so as to extend upwardlythrough the retaining ring aperture 48 when the auxiliary dispensingmember 66 is coupled to the retaining ring 40. The rigid spout 69includes an outlet or opening configured to dispense liquid from thereservoir 22.

In one embodiment, the collapsible bottle apparatus 10 includes anauxiliary thread adapter 70 that is configured to interface with abottle other than the body member 20 described above. More particularly,the auxiliary thread adapter 70 enables the auxiliary dispensing member66 or the primary dispensing member 60 to be operatively coupled toeither a conventional water bottle (FIGS. 4 a and 4 b) or a conventionaljuice bottle (not shown), it being understood that a conventional waterbottle 12 and a conventional juice bottle have a neck diameter differentfrom the other and different from that of the reservoir 22 and primarythread adapter 30 described above. The auxiliary thread adapter 70includes a side wall having a threaded outer surface 72 in a manner aswith the primary thread adapter 30 described above. The retaining ring40, therefore, may be coupled to the auxiliary thread adapter 70.

Specifically, the auxiliary thread adapter 70 includes a closed bottomwall 74 that defines an opening, the auxiliary thread adapter 70 alsodefining an open top and interior cavity between the bottom wall 74 andopen top. The auxiliary thread adapter 70 includes a first boss 76situated in the interior cavity and extending downwardly through theopening in the bottom wall 74, the first boss 76 defining a through-bore78 in communication with the interior cavity and with the opening (FIGS.4 b and 4 c). The first boss 76 provides the means for selectivelycoupling the auxiliary thread adapter 70 to a water bottle 12.Specifically, the first boss 76 includes a threaded interior surface 80that is complementary to the threaded neck 14 of a water bottle 12 so asto be selectively coupled thereto. It is understood that water from acoupled water bottle 12 may then flow through the bottle wall openingand through-bore 78 and then through the auxiliary dispensing member 66to an awaiting user.

The auxiliary thread adapter 70 includes a second boss 84 positionedoutwardly concentrically adjacent the first boss 76. In other words, thesecond boss 84 includes a cylindrical configuration, is outwardly spacedapart from the first boss 76, and surrounds the first boss 76. Thesecond boss 84 includes a threaded interior surface 86. The second boss84 defines an inner bore in communication with the bottom wall openingconfigured to receive a threaded neck of a juice bottle for engagementwith the threaded interior surface 86. FIG. 5 a illustrates theconcentric arrangement of the first and second boss, the second boss 84having a diameter that is larger than a diameter of the first boss 76.

The first boss 76 and its threaded interior surface 80 and the secondboss 84 and its threaded interior surface 82 are best shown in FIGS. 5b, 5 c, and 5 d. The second boss 84 has a diameter that is larger than adiameter of the first boss 76 which reflects the fact that a diameter ofthe neck of a conventional juice container is larger than a diameter ofthe neck of a conventional water bottle 12. In use, therefore, theauxiliary thread adapter 70 may be threadably tightened down onto eithera water bottle or a juice bottle, as may be desired or available. It isimportant to observe that when the interior threaded surface 86 of thesecond boss 84 is engaged with a threaded neck of a juice bottle, thefirst boss 76 will be received into the inner space of the juice bottleneck.

In use, the collapsible bottle apparatus 10 may be configured for use asa bottle for an infant or as a beverage container for a toddler or youngchild. For use in feeding an infant, the reservoir 22 may be filled witha desired volume of liquid, such as baby formula, by pouring the formulainto the reservoir 22 through the open top thereof while no othercomponents are coupled thereto (FIG. 2 a). The graduated indicia 26 maybe useful to a user to confirm a desired amount of liquid has beendeposited. As fluid is deposited, the reservoir 22 will expand from thecollapsed configuration (FIG. 1 b) toward the expanded configuration(FIG. 1 c). The cap 50, which may have covered the retaining ring 40 andprimary dispensing member 60 (FIG. 1 a), may be removed from theretaining ring 40 (FIG. 1 b) and threadably coupled to the body member20 (FIG. 1 c). The collapsible bottle apparatus 10 may then be used tofeed an infant in the customary manner. The reservoir 22 may be movedback to the collapsed configuration when the liquid has been dispensed,as described previously.

Alternatively, the collapsible bottle apparatus 10 may be used to obtainwater or juice from a water or juice bottle, respectively. Specifically,the retaining ring 40 may be coupled to the auxiliary dispensing member66 and then threadably coupled to auxiliary thread adapter 70. Then, theauxiliary thread adapter 70 may be threadably coupled to a water bottle12 (FIGS. 4 a and 4 b) or a juice bottle (not shown) as described above.Specifically, the water bottle 12 or juice bottle are engaged bythreadably connecting the neck of the bottle to respective threadedinner surfaces of the first boss 76 or second boss 84, respectively, asdescribed above and shown in FIGS. 5 b to 5 d.

Accordingly, the collapsible bottle apparatus 10 enables a user totransport or otherwise store all components in a purse, baby bag, orcabinet at home and to configured respective components for providing anappropriate beverage to an infant or young child.
